[Python-mode] python-mode.el interferes with GUD

This seems familiar.  I thought the topic came up before, though I thought
the conclusion was that either recent versions of python-mode.el don't
exhibit this problem or that Barry couldn't reproduce it.

Yes, please.  Can you try with the latest version of python-mode.el?  Any
chance you can try it with XEmacs of some vintage?  Neither Barry nor I use
GNU Emacs.

Thanks,
